I have my Darbee between my Integra and one input to my TV. This take care of everything that is non 4K. I have my Oppo connected to a different TV input (A sound only output from the Oppo is connected to the Integra)
The non 4K PQ is very acceptable (With the Darbee & the TV's upscaling)

I don’t understand why Darbee isn’t providing any kind of update on 4K support. We have over 300 pages of threads on the Darbee device so there is obviously a lot of interest in their technology. I don’t get why they aren’t providing their user and potential user with any kind of update. A simple 2 sentence post would be sufficient.

They have “displayed” processing of 4K material over a year ago and allude to it on their website but nothing about if it will actually come to be. It not like if they say that 1) it’s ready and waiting to be released, 2) they are still working on it, or 3) they are not going to do it... Is going to cause them to go bankrupt!

This really isn’t a trade secret here. They are one of very very few companies that provide this technology at an affordable price. I guess I don’t understand why they don’t communicate with their user base more. Provide some insight on their devolpment roadmap.

I guess my quest for a better picture may need to continue with a 4k projector at some point in the next few years.

I wouldn't give up on the darbee. As others mentioned, it could have been a defective unit. Many of us here use the Darbee in long PJ run situations with success.

I myself have a darbee on a single hdmi out of my Yammy receiver, I then have a monoprice active 1 into 2 splitter on the darbee out, and those now split hdmi outs feed my flat panel and my JVC PJ that is 25 ft away from the darbee. Had a Mits HC3800 DLP PJ working on that darbee before.

Have the darbee since it came out 5(?) years ago....working 24/7 and no issues with the remote----though I hardly use it as it's a set it and forget it type of affair.

Their founder died a few years ago and it seemed to have hit the company hard, to the point that the future of the company might be in question?

I suspect 4k enhancement is a tough job: handling all the cases without causing more problems.

You have the new resolution, but also a new color space and bit depths, plus HDR. Figuring out how to process this stuff correctly in the first place is a big job.

I don't know, but suspect that Dolby would not allow any enhancements to a Dolby Vision signal. They are keeping tight control on that.

I agree with you findings hence why the dvdo 4k mini only supports enhancement in 4k and does not do any hdr, bt2020 passthrough and they won't be releasing firmware that does even though it's hdmi 2.0.

That is very unfortunate about the founder. I was not aware of his / her passing. I really hope that they can keep the product alive and continue to implement it into future resolutions.

I do understand the complexity of 4K and it’s various flavours. It really would be great if they could design a device that could be upgraded via firmware for all these “types” of 4K streams as they have something to release. Hell even if it was a paid upgrade I’m sure most would be OK with it.

Either way it would be great to know where their heads are at with 4K processing. I’m sure I’m not the only one that doesn’t want to pull the trigger on a 5000s only to have a new 4K device released in a few months.

I agree with the 4K pass through. Would make system integration so much easier.

And maybe you don’t try to release a device that handles 100% of 4K streams. Maybe you look at releasing something that handles the majority of the 4K streams right now. The bread and butter streams. Who knows that may account for 70% of the content that is currently being consumed.

Maybe it’s unreasonable on our part to expect a device that will do everything and we just need to be educated on the complexity of that. So we can accept that a device that handles 70% is still a very much worthwhile investment.

I’m sure if the price is “reasonable” (obviously more then the 5000s) most of us on here would still buy it even if it didn’t do everything out of the box.
